I use rugs to keep weeds off garden paths and under them are non stop vole tunnels. I have no interest in killing these creature, just don't want them eating dahlia, lilium and day lily bulbs or roots. I have removed the rugs. Thinking I will use a castor oil brew on lilium, but would need caster oil by the gallon to treat my whole garden.
Suggestions?
http://wdfw.wa.gov/living/mole is an informative mole (or vole ?) site.
